  7. Abstract:
  8. Depletion of the fossil fuel resources along with the environmental concerns have led to a significant growth in utilization of Renewable Energy Resources (RERs). Among different kinds of RERs, wind energy due to maturity of its associated conversion technologies and also its widespread presence in different regions has experienced a more rapid usage in generation sector of power systems. Despite numerous benefits of this environmentally-friendly energy, uncontrollability and uncertainty in output power of wind turbines has resulted in many technical issues for operators of power systems. However, it has been shown that the presence of various storage system technologies can alleviate these technical challenges and therefore facilitate the expansion plans of wind farms in generation sector of power systems. This thesis tries to comprehensively investigate the abilities of various storage unit technologies in improving the operational reliability level of highly wind penetrated power systems. In this regard, it proposes an analytical framework to assess the short-term/mid-term reliability level of such systems aimed to assess the required spinning reserve of the system. The effectiveness of the proposed evaluation framework is validated on two modified reliability test systems, i.e. the IEEE-Roy Billinton Test System (IEEE-RBTS) and the IEEE- Reliability Test System (IEEE-RTS). These test systems are modified by adding some wind farms with different capacities to generation sector of these systems. As the next step, different operating strategies of energy storage units are introduced and the effects of these strategies on the required amount of spinning reserve in wind-penetrated power systems are assessed. By applying these operating strategies on the added storage units of the IEEE-RTS, it has been shown that how these strategies can affect the required spinning reserve of the system used to cover the stochastic nature of power systems. Moreover, the obtained results proved that the simultaneous operation of wind farms and large-scale storage units can effectively reduce the technical challenges of wind-penetrated power systems from reliability point of view
